All (6) Titanium Saddles. Titanium saddles provide a tighter, brighter tone. Recommended for guitars that are a little too dark sounding on all strings. For guitars having a naturally normal to bright tone with the current bridge all titanium is not recommended, as an already bright sounding guitar may sound TOO bright on the plain strings. For the latter, we recommend the HYBRIDge™, as that configuration will benefit any guitar.
